IMPROVEMENT lN MACHINES FOR REPAIRING HOSE, &c.l

The Schedule referred to in these Letters Patent and making parl: of the same.

l I, ALFRED SHEDLOGK, oflNew York, in thecounty and State of' New York,'have invented'a certain Improved Modeof Repairing Hose and other Knitted Goods, and Machine therefor, of which the following is a specification.

My invention consists in forming a knitted web over parts worn in hose and other knitted goods for the purpose of repairing the same, and alsoot' an improved knitting-machine therefor, giving to such repairs ,a much better appearance than whenl done by darniug, and rendering them less liable to wearl out again in the same place, as the parts knitted over are of the same elasticity as the other parts of the hose, Src., which quality the ordinary mode of mending such goods by darning does not possess.

It also enables persons purchasing a cheap vclass of goods to knit, in a short time, and with little labor, an extra thickness A,over vthe parts most liable to wear, thus vmaking such goods wear considerably longer.-

In the accompanying drawing- Figure 1 represents a piece of .knitted goods so' repaired;

Figure 2 is a back view of same; Figure 3 is a front view of my improved knitting- 'machine Figure dis a side view o'f the same v Figure 5 is a sectional view through the line :t x; Figure 6 is a View of the top of the frame and guide Figure 7 is a view of a pointed spring-beard knitvting-needle.

1n iig's. l and 2 the square dark portion a represents the web knitted over a piece of knitted goods, b, in which the hole is shown, by the light part e, in the center of the dark portion a.

The frame d, in which the needles work, stands vertically, and extending from the lower end of it is the arm di, provided with a bearing, in which the crankshaft d2 works.

n dovetails on the frame d is fitted the came, .working at a right angle `to the grooves d3 da, in which the needles work, and it is operated by the adjustable crank f, and connected thereto by the pitm'an g.

The crank f is slotted and fastened to one end of the short shaft d2 by a screw and nut, and on the other end of the shaft is xed the crank-handle`h.

On the back of the cam e is the bracket t' for carrying the thread oryarn, which, it' on a spool, may be placed on the wire il, the thread or yarn being then l passed through the friction-holes of the take-up t2 and the delivery t3. *Y If the thread is loose or in lengths it is passed through the hole in the end of wire t, the take-np t, and delivery i3.

Near the upper end of the .frame d is fitted, in a y dovetail, the piece k for holding the needles in their `grooves d da'. It is alsoextended to the top of the frame d to form a guide, k1, over which the goods being repaired are pulled, the said guide having grooves 7a2 k2, as shown at tig. 6, converging from the center line, the object of which .is to spread 'or stretch the goods as vthey .are being pulled over. The presser-frame m. isattach'ed to the frame d .hy the round pins ml ml fixed in the sides of d and passing through slots' in the frame m. `At the lower ends of the frame 'm are square slots, which t over the square pins m2 m2, ixed in d, and just below the round pins mI m1, the object of which is to hold thepresserframe m in tbe position shown at gs. 3 and 5, and it is held down by the springs msm, which are connected te the'ronndpins m m1 and pins in the sidespf the. presser-frame m..

The upper part m4 4of the presser-frame m lies over the top ot' the `frame d, and is formed so as tc close Vthe spring-beards ofthe needles as they descend. l t

is also provided with a series of projections, which lie; between and prevent the needles from raising the goods as they pierce it. The goods are also held between the guide-ltL and presser m4 by the springs m3 m3. lThe presser m4 is provided with grooves corresponding to the grooves k2 It? on the guide k1. A

0n the back of d are cast the lugs d* d5; through the lower one is the screw d6, for clarn ping the machine to the table.

For repairing different-sized holes a certain number of the needles on each side maybe dropped from the cani e into the straight slot el by loosening the nut which holds the adjustable crank f to the shaft d and setting the came over so as to bring the' openings e2 e2 opposite the lower ends of the needles to be dropped,

then set the adjustable crank so as to just'work down the cam eis then moved by turning the handle il. so as to raise thev needles through the goods'. The hooks on the ends of the springs n n, of which ,there vare two or more, are hooked in the goods, and then, by turning the handle h, the thread-delivery lays the thread under the beards of the needles, and they draw it down through the goods by the cam e acting on their lower ends, which are bent, as shown at figY 7, so as to enter the cani-groove, the presser 'm4 closing the spring-beards of ,the needlesas they pass it.

When the needles commence to rise again the loops they each form are slackened, so that the springs n a draw the hose, 85o., over tothe extent of the loops,

the needles again piercing the goods a little in front of' the first-row of stitches, and, again taking the thread and moving down with it through the goods and loops already formed, discharge the `irst loops over the tops of the needles, the springs n n again drawing the goods over to the extent of the loop, and so' on until the hole is knitted over or the extra thickness Worked on the parts, asdesired.

To nish off the patch all that is necessary is to draw the end of the thread or yarn through the last row of loops'with a common needle or hook provided therefor similar to a crochet-hook.

. The object of the take-up t2 is to'keep tue thread or yarn always taut between tbe delivery and the needles.

The wires oo are for keeping the hose, dtc.,'o1` from the working parts of the machine.

' Fig. 7 represents a pointed spring-beard needle,

-which may be used, if found necessary, enclose-knitted goods.'

I claim-- 1. The combination ofthe row ofneedles, presser 1n", and guide lol, operating so as to knit patches on knitted goods, for the purposes lof repairing and strengthening the same, substantially as described.

2. The springs n n, in combination with the presser 'm4 and guide k1, substantially as described.

3. The presser 'na-,provided with a series of projections, which lie between and prevent the needles from raising the goods as they pierce'it, substantially s d escribed.

4. The guide k1, in combination "with the presser m4, substantially as described.
